About the TCMO2: TCS Mo-based Alloys Database

TCS Mo-based Alloys Database (TCMO) is a thermodynamic and thermophysical properties database for molybdenum-based alloys and superalloys. All necessary volume data (including molar volume and thermal expansivity) for various alloy phases is available. The database also comes with the description of electrical resistivity and thermal conductivity, as well as surface tension and viscosity of the liquid.

TCMO2 Thermophysical Properties

Molybdenum-based alloys are used in various applications due to their excellent mechanical, thermal, and corrosion-resistant properties. They are commonly used in aerospace components, electrical contacts, industrial machinery, and high-temperature furnace parts. Additionally, they are used in the production of high-strength steel alloys, which are crucial in construction and automotive industries for their durability and resistance to corrosion and heat.

The molybdenum-based alloys databases are available for refractory (e.g. Mo-base) superalloys that function at higher temperatures than the Ni-base superalloys. The molybdenum databases include the silicide and borosilicide phases to form SiO2-based scales, which is to overcome the challenge of poor oxidation resistance that happens with these alloys that contain MoO3.

The database can be used with our entire suite of products: Thermo-Calc, the Add-on Diffusion (DICTRA), Precipitation (TC-PRISMA), and/or Additive Manufacturing Modules, and all available SDKs.

The thermodynamic database is compatible with the corresponding mobility database TCS Mo-based Alloys Mobility Database (MOBMO) that provides kinetic data for those working with the add-on kinetic modules – the Diffusion Module (DICTRA) and the Precipitation Module (TC-PRISMA) – as well as a few specific calculation types, such as Scheil with back diffusion. The current version of the mobility database is MOBMO2.

It is possible to combine several databases to make calculations using Thermo‑Calc. For more information related to a specific type of problem, contact one of our support specialists at info@thermocalc.com. The experts are available to make recommendations on the most suitable database to use for your needs.
